A) \[\frac{27}{8}\]
B) \[\frac{9}{4}\]
C) \[\frac{3}{2}\]
D) \[1\]
Correct Answer: B
Solution :
Required heat,\[Q\propto {{r}^{2}}\]where r is the radius. \[\therefore \] \[\frac{{{Q}_{1}}}{{{Q}_{2}}}=\frac{r_{1}^{2}}{r_{2}^{2}}\] \[\frac{{{Q}_{1}}}{{{Q}_{2}}}=\frac{{{(1.5)}^{2}}}{{{(1)}^{2}}}\] \[\frac{{{Q}_{1}}}{{{Q}_{2}}}=\frac{9}{4}\]You need to login to perform this action.
